Bro I'm a ballplayer too, at your age I was playing a high-caliber, please listen to what guys are saying.
Winstrol V dries out muscles and tendons and joints, things that you can't afford to have happen if you are playing ball at a competitive level, you'll end up hurting yourself much more easily.
Winstrol V alone will shut down your natural testosterone production, and at 19 years of age you don't want to mess with it. Low testosterone production will leave you feeling sluggish and depressed, unable to keep erections, and will cause you to lose any gains that you made.
People often have very little real information when first being introduced to steroids, I myself was led completely astray by my friend the "expert",..luckily I found this site and got some great advice.
Best of luck.
